Abstract
Many equations to predict drying shrinkage of concrete have been suggested. However, it is not completely clear about the quantitative relation between drying shrinkage strain obtained by equations and the value of drying shrinkage for member.
In this paper, we deal with a simple method to predict drying shrinkage strain for member, which drying shrinkage strain is to be obtained by using the experimental data in the past or the result of length change test specified by JIS, with consideration for influence of construction times, thickness of member and reinforcing bar arrangement. The following became clear after the investigation on the influence of thickness of member and reinforcing bar arrangement on drying shrinkage of the wall structure which have been constructed in winter. The restraining actions of reinforcing bar on drying shrinkage can be evaluated by using empirical equation. The restraining actions of reinforcing bar increase as the amount of it increases and the tendency becomes gradual as the thickness of member becomes thick.
